Answer:

x = 28/3

Step-by-step explanation:

We can solve this problem by using similar triangles:

Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.

Now we can set up ratios and solve:

13/7 = (x+8)/x

multiply both sides by x:

13x/7 = x+8

Multiply both sides by 7:

13x = 7x + 56

move the 7x over and divide by 6:

6x = 56

x = 28/3

Answer:

9 1/3 or 9.3333333333

Step-by-step explanation:

Triangle ABC is similar to Triangle ADE because they are proportional.  It is a 7:13 ratio as shown by segments CB and ED.

Therefore, the ratio from AB to AD would also have to be 7:13.  The ratio as shown by the picture is x:x+8.  Therefore x:x+8=7:13.

Now you put this in fraction form.  \frac{x}{x+8}=\frac{7}{13} You multiply both sides by X+8 and get X=\frac{7x+56}{13}.  Now you multiply both sides by 13 and get 13X=7x+56.  Now you have cleared the fractions so it looks neater.  Next, you subtract both sides by 7x and get 6x=56.  Finally you divide both sides by 6 and get x=9 1/3

Answer:

<h2><u><em>The lengths of the sides of a small cube are = foot. Volume of cube = side x side x side. V = = cubic foot. Number of small cubes that can be packed in the prism = = = = 180 cubes. Hence, 180 cubes can be packed into rectangular prism. Part B: Unit cube volume is 1x1x1 =1 cubic foot. So, 180 cubes will have 180 cubic foot volume.</em></u></h2>

You are running a fuel economy study. One of the cars you find is red. It can travel 24 4/5 miles on 4/5 gallon of gasoline. Wha
Lilit [14]

Answer:

1) 28.4 miles per gallon

2) 34 miles per gallon

3) the red car

Step-by-step explanation:

Blue car:

Travels 35 1/2 miles on 1 1/4 gallons of gasoline

Red car:

Travels 27 1/5 miles on 4/5 gallons of gasoline

We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:

Blue car:

(35 1/2) / (1 1/4) = 28.4 miles per gallon

Red car:

(27 1/5) / (4/5) = 34 miles per gallon

The red car travels greater distance with 1 gallon of gasoline {and thats about it!}

Evaluate f(t)=-2t2+ 1 for f(-3).
podryga [215]

Answer:

7

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

f(-3)=-2(-3) +1

Second, multiply -2 and -3 to get 6:

f(-3)=-2(-3)+1⇒f(-3)=6+1

Third, add 6 and 1 to get your answer:

f(-3)= 6+1⇒f(-3)=7
